IMPROVEMENT IN CULTIVATORS.

The Schedule referred to in these Letters Patent and making part of the name.

To all whom it may concern: y

Be it known that I, JOSEPH ADAMS, ofv Manteno,

` in the county of Kankakee and State of Illinois, have invented a new and useful Improvement ln Cultivators; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art tb make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure l is aside view of my improved cult-ivator, partly in section, through the line n: x, iig. 2.

Figure 2 is a top view of the same.

Figure 3 is a detail sectional view of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved cultivator, which shall be so' constructedand arranged that the plows may be easily adj usted closer together or `further apart, andraised or lowered, to regulate the depth at which they work in the ground;

It' consists in the construction and combination of various parts of the machine, as hereinafter more fully described. y

Aare the wheels, the axles B of which are bent upward nearly at right angles, and the upper ends of which are connected by aright-and-left screw, O, which passes through holes in the said upper ends, so that the axles B, and, with them, the plows, may be moved -toward or from each other by simply turning the screw C.

'lhe screw'Ckinay be turned by means of a' handle or level', D, `formed upon or attached to its middle part.

E are the bcams,.the rear parts of which are curved downward, so as to serve as standards for the attachment of the shovel-plows. l

Ihe forward ends of the beams or bars E are jointed to nuts, F, through which the crank-screws G pass, so that, by turning thc said screws 'G in one. or the other direct-ion, the forward ends of the plow-beams may be raised and lowered, as desired, to regulate the depth at which the plows run in the ground H are the shovel-plows, to the rear sides of which are riveted, bolted, or otherwise secured, loops or keepers, I, through which the lower ends of the standards E pass.

and pressing against the said standards E, as shown in fig. 1. a

K are the handles, which are attached to the curved part of the beams E, and which are 'strengthened and 1 held in proper position by braces L.

lhe handles K, one or both, are bent or inclined to one side, so that the operator, while guiding the plows, may walk at the side of the row being cultivated.

lhe lower ends of the screws Gr are swiveled to the horizontal parts of the axles B, and 'their upper ends revolve in arms or supports, b', attached to the upper parts of said axles B, as shown in gs.`1, 2, and 3.

To the upper endsof the swiveled screws G are at-` tached, or upon them are formed,cranks g,"by means of which the said screws are operated.

M is the tongue, the rear part of which is branched, and tothe said branches are attached the upper parts or ends of the axles B.

The connection between the branches of the tongue M and the axles B b is strengened by the braces 'm1, as shown in the drawing.

The. rear parts of the branches of the tongue Mextend back, and to their rear ends areattached hooks,

m2, upon which tlie plow-beams may be hooked to t support the plows above the ground when passing from place to place.

Havinglthus described my invention,

I claim as new. and desire to secure byv Letters Patentl 1. The crank-screws G and nutsF, to whiehthe forward ends of' the plow-beams are jointed, in combination with the frame-work of a cultivator, substantially as herein shown and described, and for the purpose set forth.

2. The right-andleft screw C, provided with a lever or handle, D, in combination with the adjacent ends of the axles B, substantially as herein shown and described, and for the purpose set fort-h.

3. An improved cultivator, formed bythe combination of' the wheels A, axles B, right-and1eft screw, G, provided with a handle or lever, D, plow-beams E, jointed to the nuts F, and swiveled crank-screws Gg', with each other, and with the branched tongue M,sub stantially'as herein shown and described.
